Product Information
GoBoard® 1-5/8" Hi-Lo Fasteners are designed to secure GoBoard tile backer board to wood studs and wood subfloors. Their Hi-Lo threads increase holding power while reducing driving torque for reliable attachment across residential and commercial tile installations.
Each screw features a large-diameter head that distributes holding force across the panel surface. The smooth underside helps the head seat securely against the GoBoard panel while reducing the risk of overdriving and damaging the board surface.
The corrosion-resistant construction supports long-term performance in tile assemblies. These fasteners work with 1/4", 1/2", 5/8", and 1" GoBoard panels, and each 550-piece contractor pack includes the required T-25 Torx driver bit.
Common Questions
The 1-5/8" Hi-Lo fasteners work with 1/4", 1/2", 5/8", and 1" GoBoard panels. Select the panel thickness required for the wall, shower, ceiling, floor, or countertop installation and follow the current GoBoard instructions for that specific panel and application.
No. This Hi-Lo version is designed for wood studs and wood subfloors. GoBoard self-drilling fasteners are the corresponding option for metal studs. Choosing the correct fastener style helps ensure that its threads and point engage the intended framing material properly.
Yes. These 1-5/8" Hi-Lo fasteners can secure compatible GoBoard panels to wood subfloors as part of the specified floor installation. They are not required over concrete subfloors. Follow the current GoBoard instructions for mortar, panel spacing, fastener placement, and perimeter distances.
GoBoard Washers are optional with these fasteners and may be used when the application calls for additional holding strength or a washer-based fastening schedule. Because spacing requirements vary by fastening method, follow the current GoBoard instructions for the selected panel and installation.
GoBoard Fasteners are generally installed at a maximum spacing of 8 inches. Fasteners must also remain within the required distance from panel edges. Spacing can differ when washers or alternative backer board screws are used, so follow the current instructions for the specific assembly.
Use the included T-25 Torx bit with a variable-speed corded or cordless drill or screw gun. Adjust the clutch so each fastener sits flush with the GoBoard surface. Do not overdrive the head through the panel facing because this can reduce holding performance.
Yes. Every fastener penetration must be sealed when the GoBoard assembly needs to be waterproof. Cover each location with GoBoard Sealant, GoBoard Pro Sealant, or an approved alternative according to the current installation instructions before installing the tile.
Each contractor pack includes 550 corrosion-resistant 1-5/8" Hi-Lo fasteners and one T-25 Torx driver bit. GoBoard Washers and sealant are separate accessories, so confirm whether they are needed for the panel layout and waterproofing method before beginning the installation.
